IMPROVEMENT 1N c'uL'rIvAToRs.

The Schedule referred to in these Letters Patent and making part oi' the same.

To allwhom it may concern:

-.'Be it known that I, ISAIAH BENTON, of Shelbyville, in thecou'nty of Shelby, and State of Illinois, have 4invented a new and useful'lmprovement in Cultivators; and I do hereby declare that th'e following is a f ull, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specication, in which- AFigure l is a vertical longitudinal section of my improved machine, taken through the line :z: x, fig. 2.

Figure 2 is a top or plan view. of the same, parts being broken away to show the construction, Similar letters of reference indicate like p arts. v

My invention has for its object to improve the construction of my improved cultivator, patented March 6,' 1866, numbered 52,998, so as to make it more convenient, satisfactory, and ecient in operation; and -It consists in the construction andcombination of various parts, as hereinafter more fully described.

"A'are'thewheels, and ,B is the axle. of the cultivator.

O is the frame, which is' rigidly attached to the axles B, and totheforward pai-tof which the tongue D is attached.

E are the plow-beams; to the rear parts of which are secured the standards F, to which the plows G are attached.

j arewedge-shaped blocks interposed between the standards F and beams E, so that by turning the said blocks half around, the plows-may be so adjusted as to throw the dirt towards or from the hill, as may be desired.

To the rear part of the beams 'E are attached uprights H, which pass up through keepers attached to the pivoted bars or frame I, so that the beams E may be made to move up and down vertically, and be car- -ried with thesaid bars or frame I, as they are vibrated upon their pivoting points.

' The forward ends of the beams E are connected to the forward ends of the bars I by the curved bars, stirrups, or plates J, the upper parts of which are securely attached to the forward ends of the said bars I, and to the lower parts of which the forward ends oi the plow-beams E are pivoted, so that the rear ends of said beams E may be free to movevertically, independently of the bars I, but can only move laterally the inner ends of which in connection with the said rear ends' of the said bars I.

.The forward parts of the bars I are pivoted to the forward p art of the frame O by bolts, and they are also connected to each other by the adjustable bar K.

' The rear parts of the bars or frame I rest upon the axle B, or upon .a cross-bar of the frame C.

L are adjustable connecting-bars, the outer' ends of which are pivoted to the rear part of the bars I, and are pivoted to the end of the arm M, the other end of which is rigidly attached to or formed solidly upon the foot-lever N,

The foot-lever N is pivoted at its middle part to the middle part of the' axle B, as shown in fig.,1.

.O is the' drivers seat, which is supported from the frame Cin such a position that the drivers feet may rest upon the ends. of the foot-'lever N, so that by pressing upon-sad lever with one or'the other of his feet, the driver may' move the plow-beams .and plows toone side Yor the other, to avoid irregular hills or obstructions when operatingthe machine.

P are levers pivoted to the outer sides of the pivoted bars I, and the forward ends of which are connected with the plow-beams E by short chains Q, the

-lower ends of which aresecured to the said beams E,

and the upper ends of which hook uponhooks attached to Orformed upon the ends of the levers I).

rlhe rear ends ofthe levers Pare adj ustably pivoted v.to the ends of the' cross-bar'R, as shown in figs. 1

and'2.

Bythisconstruction, the driver, by bearing down upon the cross-bar R, with one or the other foot, or

, with both-feet, can conveniently raise either or both plowbeams as he may desire, for convenience in passing overobstructions, turning around, or passing from place to place.

- Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- 1. The combination oi. the pivoted levers I, pivoted cross-bar It, and chains Q with cach other, and with the pivoted-bars I and plow-beams, E, substantially as-herein shown and described, and for the purpose set forth. l

Witnesses: ISAIAH BENTON.
